can the unbalanced Pi attenuator take the place of isolator - RF Cafe Forums
Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.
Below are all of the forum threads, including all the responses to the original posts.

Post subject: Pad substituting for isolatorPosted: Mon Jul 18, 2005 6:55 pm
While a 30 dB pad would give 30 dB of isolation, I'm hard-pressed to come up with a situation where that would make sense.
In a receiver, that would give a 30 dB noise figure: terrible!
In a transmitter, that would reduce the power output 30 dB: what a waste!
What is the context for this question?
